[texts]Preprocessing of Configuration Space for Improved Sampling Based Path Planning - Titas Bera, M. Seetharama Bhat, D. Ghose
Sampling based planners have been successful in path planning of robots with many degrees of freedom, but still remains ineective when the configuration space has a narrow passage. This paper presents two new techniques of preprocessing the configuration space. The first technique called a Random Walk to Surface (RWS), uses a random walk strategy to generate samples in narrow regions quickly, thus improving eciency of Probabilistic Roadmap (PRM) based planners...

[texts]Mobile Robot Navigation Using a Combined Optimized Potential Field and a Boundary Following Algorithm - Samer Charifa, Marwan Bikdash
We propose a novel method to the navigation of mobile robots that combines a modified potential field method with a boundary-following algorithm. The resulting method avoids many of the pitfalls of each component method, such as entrapment in local minima, oscillation in narrow corridors, hugging obstacle boundaries inefficiently, and low-quality velocity and acceleration profiles. The proposed harmonic field has non-uniform boundary conditions based on the length of the shortest path to the tar...

[movies]MIT 6.832 Underactuated Robotics, Spring 2009 - MIT OpenCourseWare
Instructor: Russell Tedrake Robots today move far too conservatively, using control systems that attempt to maintain full control authority at all times. Humans and animals move much more aggressively by routinely executing motions which involve a loss of instantaneous control authority. Controlling nonlinear systems without complete control authority requires methods that can reason about and exploit the natural dynamics of our machines...
